Zur Strukturchemie der Diperoxovanadate(V): Das μ-Hydroxo-bis [oxo-diperoxovanadat(V)] Anion / Studies on Diperoxovanadates: The μ-Hydroxo-bis [oxo-diperoxovanadate(V)] Anion

Abstract

Abstract Depending on the pH and the respective concentrations of solutions containing NH4+/NH3/H2O2/NH4VO3 three yellow ammonium salts can be isolated: (NH4)4[O(VO(O2)2)2], NH4[VO(O2)2NH3]; and the novel (NH4)3[HV2O11] · 2 H2O. A cesium and potassium salt of the latter anion have been prepared. The infrared spectra of these salts are interpreted assuming a μ-hydroxo-bis[oxo-diperoxovanadate(V)] structure in the solid state.
